PHASE-CHANGE SUSPENSION FLUID COMPOSITION INCLUDING POLYETHYLENE OXIDE PARTICLES AND METHOD FOR MANUFACTURING THE SAME

摘要

A suspension fluid prepared by dispersing polyethylene oxide particles into a solvent including water and one or more types of compounds selected from the group consisting of ethylene glycol and propylene glycol, and a method for manufacturing the same. The phase-change suspension fluid can be a shear-thinning fluid showing a constant newtonian behavior in a low shear rate or low frequency region, but showing a non-newtonian behavior appearing as liquid-like suspension in a high shear rate or high frequency region due to viscosity decrease, and is capable of reversible phase changes by the vibration of a vehicle, and therefore, may provide effects of having advantages of a hydraulic bush in a low frequency region and also having advantages of a solid bush in a high frequency region.
